Frequently Asked Questions

Do you have special plans for open source projects,
non-profits, groups of friends, and other non-commercial
entities?

Yes! Zulip Cloud Standard is free for open source
projects and affiliated institutions. We also offer
steep discounts to non-profits, educational
institutions, groups of friends, and in scenarios where
most of the users are not paid employees (e.g. company
support forums). Just contact sales@zulipchat.com and
we’d be happy to discuss your situation!

Yes! Some of our biggest fans have hundreds or thousands
of users, including Fortune 500 companies like Akamai,
and open source communities like
The
Recurse Center. If you'd like to see a large Zulip
in action, the
Zulip
community server has thousands of accounts and hundreds of weekly active users, and is run on a single machine with 8GB of RAM.

Can I pay by credit card and/or invoice?

You can always use a credit card to pay, and we can bill
by invoice for amounts over $1000.

Can I start on Zulip Cloud and later move to On-Premise?

Yes! Our high quality export and import tools
(cloud,
on-premise) ensure you can always move
from our hosting to yours (and back). If
you’d like to do a migration, email
support@zulipchat.com and we'll get you started!

Who can I contact if I have further questions?

Zulip
community server to see Zulip in action and chat
